MACHINE FOR WIRING BLANKS.

SPECIFICATION forming part of Letters Patent No. 6335,356, dated October 24, 1,899.

' 7 Application filed February 18, 1898- Berial No; 670.835. (No model.) i

To all whom itmwy concern:

Be it known that L'EDWARD P. SHELDON, a citizen of the United States, residing at New York, (Brooklyn,) county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Wiring .Blanks, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

Myinvention relates particularly to the attachment of wire openers to blanks from which are to be made or which are to be attached to envelops, wrappers, boxes, or other articles of paper, cardboard,-wood, cloth, or other readily-severable material by the use of which such material may be readily cut on a desired opening-line and the package formed thereby opened; and myinvention includes the devising and adaptation of mechanism whereby such wire may be mechanically attached to the blank with which it is to be used in such a manner as to-enable the wire to be used in cutting the blank for opening the package by pulling on the wire. 4

While wire openers such as I have above referred t9 have been heretofore suggested, no mechanism, so far as I am aware, has been devised for mechanically attaching them to blanks. I use the term mechanically attaching in this specification and the claims to distinguish from attaching a wire opener toa blank by glue or similar material, as in the case of the string openers applied by such means, for which work machines have been patented and by which machines it has been suggested that wires might be similarly secured.

My invention also includes the'organization of a machine wherein the several operations which require to be performed in -connection with the attachment of the wire opener to the paper may be automatically carried out. Thus it is generally necessary to apply gum or other I adhesive material tot-he paper blank for making the package, and it is desirable in order to produce a completed product at one operation that the gumming mechanism should beends of' the wire to the envelop in order that it may not be necessary for the. person using the openerto make a selection between the.

' ends, nevertheless'Ido not wish to limit mypart of the same machine as the wiring mechanism. It is also frequently desirable to fold the paperafter 'the Wire is applied thereto in order 'to'form it'into a receptacle;

My present invention therefore includesthe .devising of an organized machine having in combination mechanism for performing all .of these three functions or the wiring in com;

bination with either a gummingor a foldingmechanism and also mechanism for transferring the blank from each of said mechanisms to the next. It will, however, be understood that I do not limit myself herein to the use of a gumming or a folding mechanism in con-.

nection with the wiring mechanism or to the use of either of these mechanisms in connection therewith. If it is desig'ed; the wiring mechanism may be used by i self or in com-' and without reference to the special construc-' tion of any of the mechanisms.

While it is not essential to my invention, broadly considered, that any special type of machine for mechanically attaching the wire opener to the blank or a machine for making such attachment in any special mannershould be em ployed, still it is a part ofmy' invention, considered within narrower limits, to provide a machine which shall be capable of attach- 'ing the wire by causing it to penetrate the material twice and bending it down thereafter,

so that there shall be three parallel strands wire at the point of attachment to the paper. To this end my invention includes means for feeding the wire, cutting therefrom a proper length, ben'dingdown the ends or an end thereof, and causing the same to penetrate the paper, used in connection with mechanism for causing the bent portion of the wire to agaifi'penetrate the paper, and for thereafter bending over the e n'al' thereof and clenchingthe.same. g 4

While it- 'is generally desirable to attach both .wire opener to any sort of a blank to be used for any purpose. This blank is usually and preferably of paper, but may be of any other suitable material, as cardboard, thin wood, or cloth. plied to any of a large variety of uses, among which I may specify envelops, newspaperwrappers, labels, or sealing-strips for boxes, &c., some of which uses are set forth in Patent No. 562,336, granted to Frank E. Munn.

In the drawings, Figure 1 is a side view of an envelop-machine wlth the mechanism for attaching the wire to the envelop mounted on it, the reel for carrying the wire-supply being broken to show other parts of the mechanism. Fig. 2 is a plan view of the envelopmachine and wiring mechanism as shown in Fig. 1. 'Fig. 2 is a front view of the wirereel and wire-take-off mechanism,-the view being taken on the line 2 of Fig. 2 looking in the direction of arrow. -Fig. 3 is a longitudinal section of the upper part of the machine, taken on'the line 3 3 of Fig. 2, showing the table of the machine and the several mechanisms for gumming, transferring, wiring, and folding the envelops, this view showing the mechanisms on a larger scalethan Figs. 1 and Fig. 4 is a horizontal section on the line 4 4 ofFig. 3.

Fig. 21 is an end view of the same. Fig. 22 is a section on the line 22 of Fig. 19. Fig. '23 is a front View similar to Fig. 22, parts being removed to clearlyillus trate the mechanism. This view shows the fingers for bending the ends of the wire preparatory to its being forced through the envelop-blank to be clenched, also the plungers for forcing the ends through the blank and the sliding plate by which the plunger-s are carried. Fig. 24 is a plan view of Fig. 23. Figs. 25, 26, and 27 are details showing devices for accurately guiding the ends of the wire to be bent. Figs. 28, 29, and 30 are details of wirebending fingers and su pport. Fig. 31 is a section taken on the line 31 31 of Fig. 6, showing in detail the wire-feeding devices and mechanism for driving the same. Fig. 32 is a section on the line 32 32 of Fig. 6, showing the cam-shaft and arrangement of cams on the same for operating the several mechanisms. Figs. 33 to 44 are front and sectional views showing the positions of .the different parts during different stages in the operation of cutting, bending, and clenching the'end of the wire nearest the feeding mechanism, the positions of the parts at the other end of the wire being the same except that there-is no cutter at the latter end. Figs. 45 to 47, thelast a section on line 47 of Fig. 46, show a modification in which the wire-clencher is pivoted and has a swinging instead of a vertical movement. Figs. 48 to'50 show a swinging clencher of a slightly diiferent construction. Figs. 51 to show a modified construction in which the body portion of. the Wire length forming the opener is caused to take a position slightly out of line with that portion of the wire length to be bent to form the legs of the opener, this arrangement being for the purpose of causing the wire ends when inserted through the blank for the second time to pass the body portion of the opener without the assistance of a spring or other guide, Fig. 51 being a horizontal sectionthrough the wire-channel, Fig. 52 being a section on the line 52 of Fig. 53, Fig. 53 being. section on the line 53 of Fig. 51, Fig. 54 being a horizontal section through a part of the wire-channel just before the clenching of the wire, and

Fig. 55 being a'vi'ew similar to Fig. 53 except that the clencher is just about to descend. Figs.'56 to 61 illustrate another modification in which the clencherand the recess in which it moves are set diagonally, so as to cause the end .of'the wire length formin'g the opener to lock across the body portion of the wire when clenched Fig. 56 being a side elevation,partl y .in section, of this construction of mechanism,

Figs.

62 to 65 show a modified construction adapted. to bend the ends of the wire when the.- latter are bent to force the wire through the blank asecond time in an outward instead. of in an inward direction.

Referring to Figs. 1 to 4, A is the frame of the machine, upon which is mounted the table- B. At one end of the table B is mounted the gumming mechanism 0 and at the other end the folding mechanism D. These .mecha-m' isms are operated from 'the,main drivingshaft E by cams and connections, the cams not being shown, but being well known in, connection with this form of mechanism. The pile of envelop-blanks X are placed on a feeding-table a, said table having a vertical step-by-step feeding movement. Positioned just above the table a and over the blanks are two gumming-fingers 0 c, the bottom SHE-- faces of which receive gum from a duct-roll d, reciprocating between two fountain-rolls in gum-boxes e d. This duct-roll d is carried by 'sleeveswhich slide on the guide-rods'ff', these sleeves being connected by links to'the ends of two vertical rock-arms g 9, carried on the rock-shaft h and operated through suitable connections by a cam (not shown) carried by the driving-shaft E, as shownin Figs. 1 and 2. The gumming-fingers 0c are carried by a cross-bar fixed to a vertical rod d,,sliding in a bracketj. The gum being applied to the bottom surfaces of the fingers by roll (1, the fingers will be moveddownw'ard to apply the gum to the flaps of the envelop blank by means of. links It and rock-arms Z Z, mounted on the rock-shaftsnn, the rockshaft n being rocked by a cam (not shown) on the main shaft E through link 0. (Partially shown in Figs. 1..and'2.) The fingers c 0' reciprocate vertically through openings in the horizontal plate 19, connectingthegum-boxesu When the gumming-fingers have applied gumto the blank, theywill then retreat and move upwardly, carrying. the. blank with them, it being held fast to the fingers at this time by the gum. The fingers move up untilthe blank has been positioned over and into the path of a reciprocatihg carrier M, consisting of two rods m m. arrived under the raised blank, the blank of the plate p, throughwhich the fingers rise, and by rocking fingers q q, mounted on the rock-shaft 1", these fingers operating tolay the blank on the carrier-arms This shaft T, which is rocked from the shaft E through suitable 'connections,-also actuates ,the pawl-and-ratchet feeding movement b of the table athrough arms 8 s. The blank willnow be droppedronto the-carrier MI which runs quite close to the stripping-plate 10, so, that the distance the blank-drops is very slight.. The carrier will then be moved to the. left, (see Fig. 1,) first to the'wiring mech to. the disk 81.

Whenthe carrier M, has I am'sm and then to-the folding devices D,'

where the blank will then be folded to envelop form by the plunger I and foldingwings J (see Fig. 3) in the usual manner. The carrier M is reciprocated between the gumming and the folding devicesby means of linkt, arm 16, cam-lever u, and cam don the driving-shaft E, as shown in Fig. 1.

The mechanism for attaching the wire'to' the blank will nowbe described in detail, reference being had first to Figs. 5, 6, and 7-, whichshowtheusevera-l mechanisms assembled for that purpose;

Adjustably secured to thetab'le B of the machine is a supporting-frame 100, in which is mounted one end of a shaft 80, the other the bracket 101 and normally held in 'engagem'ent with the disk 81 by a spring 85,'fast at one endto the lower part'of the arm 83 and at the other end to the frame 100. -The arm 83 carries an adjusting-screw 86, which engages a stop 87 for properly adjusting the disk 82 with relation The wire -y is fed in a continuous strand from the wire-reel Y in a man her hereinafter described to a guiding-tube 88, thence between the feeding-disks '81 82, which feed the proper amount of .wirerequired,when the lower disk will be-swu'ng downward outwardly on thepivot 84 by a cam 90, fixed to shaft 80 and which engages a disk '91, fixed to the stud 92, which is carried in a sleeve 93, formed on the swinging arm 83,1;he stud 92 also carrying the feeding-disk 82, as shown in Figs. 7 and 31.

The different parts of the mechanism shown as carried by the shaft 80 are. so arranged. that the feeding-disk 81 will feed the proper lengthof wire during one-third of a revolu tion of the shaft 80, leaving two-thirds of each revolution for the other parts to perform their work, as hereinafterdescribed. Asone-third of the circumference of the feeding-disk 81,

the length of wire necessary if driven by shaft 80, it is, as previously stated, mounted. to roas it is shown, would not besuficient to feed will be stripped from the fingers c c by means ,1 2 0 tare freely on shaft 80 and is driven at'a higher rate of speed than said shaftby-means of-a gear-wheel 94, keyed tothe shaft .80 and meshing with a pinion 95, mounted'loosely on a short shaft 96, fixed in the frame -l0() and con-.- nected by a short sleeve 97130 a larger pinion I. 98, which engages a gear-wheeli99, somewhatsmaller than the wheel. 94, said wheel 99 b'eing fast to the feeding-disk 81-. This form' of gearing, as will be seen,igive'sto the disk 81 ahigher rate of speed than the shaft 80 anda 'zsnfiicient contact with the disk 82 tofeed the right length of wire before the cam'QOoper' 'with the disk 81.

ates to throw the disk 82 out of engagement The feeding -disk 82 is driven at the same surface speed as disk 81 by a pinion which meshes with the gear 99 of the feeding-diskSl.

The wire is fed from the feeding-disks 81 82 through a guideway formed of a plate 102, having a groove 103 along its bottom face for the passage of the wire, the wire being held in the groove 103 by an inwardly-extending bottom flange 104, formed on a removable cap-plate 105, which hasa top flange 100 resting on a fixed abutment 107'and held in po sition by a pivoted arm 108, as shown in Figs. 3, 5, and 8. The guide-plate'102 is fixed accurately to the flange 104 by dovetailed pro jeotions 109, formed on the bottom face of the plate 102, these projections entering corresponding grooves in the flange 104:.

The mechanism for cutting and giving the first bend to the ends of the wire and the devices for holding the .same in position while being cut and bent and for moving the bent wire down and through the envelop-blank will now be described, reference being bad particularly to Figs. 5 to 18.

The wire on being fed will pass over a short swinging table 110, thence over a long swinging table 111, underneath a top plate 112, having a groove 10 formed in its lower side the entire length of the table, the tables 110 111 and plate 112 forming bottom, top, and side guides for the wire as it is being fed. The swinging table 111 has at either end a plate 113, by which it is swung outwardand away from the plate 112 in a manner hereinafter referred to. The tables 110 111 are pivoted on a stationary bar 114, having a coiled spring 115 mounted on it, the,inner end of said spring 115 bearing against the table 111, and the other end is fast to one of the bearings 116 of the bar 114, the tendency of the spring being to normally press the table 111 upwardly against the bottom face of the plate 112. f The short table 110 forms a short bridge for the passage of the wire between the end of the guide-plate 102 and the inner end of the table 111.

Fixed onto the'frame G are two vertical guiding blocks 75 76', having guideways formed in them, in which reciprocate vertically two sliding plates 70. The slidin plate 60 has at its ends, as shown in Fig. 16, two downwardly-extending legs 77 78, the inner one, 77, carryingacutterplate 119, set in flush with'the surface of the legs and having a cutting edge 120 normally resting just above the line of movement of the wire, as shown in Figs. 11, 12, and 16. The legs 77 78' are each grooved horizontally on their lower edges at 15 and 16 and vertically on their inner edges at 17 18', as shown in Figs.

11 and 12 and in dotted lines in Fig. '16, the

horizontal groove 15 forming a top and side guiding-surface for the wire during its passage across the table 110 and the groove 16 a top and side guiding-surface for the end of the wire which passes beyond the table 111, the portions of the wire resting in these grooves being those portions by which the wire is attached to the blank. The vertical grooves 17-18 on the inner edges of the legs 77 78 receive and guide the bent portion of the wire after being cut and during the downward movement of the slide 60 to perform such bending, as shown in Fig. 35.

The sliding plate 60 is moved toward and away from the blank which rests on the carrier-arms in m (see Fig. 5) in the following manner: At the upper end of the plate 60 is fixed a stud 121, which is engaged by the forked end of an arm 122, mounted loosely on a rock-shaft 123, journaled in the guide-block 75. The arm 122 is rocked by a-second lever 124, which is also loosely journaled on the rock-shaft123outsidethearm 122. Theouter end of the lever 124; engages a stud 125, fast to the arm 122 and which, as shown, is positioned about midway on the arm between the stud 121 and the rock-shaft 123. The end of the lever 124 has a slot 10 formed in it, through which the stud 125 passes and upon which bear the inner ends of two set adjusting screws 20. The inner end of the lever 124 carries abowl 126, which engages a cam-disk 127, carried by the shaft 80 and so formed and positioned on the shaft 80 that theslide 60 and parts coacting with said slide will commence to operate at the proper time-thatis, just after the wire y has been fed into position across and over the blank 00. It will be seen that by'having the arm 122 separated from and operated by the lever 124. through the ad justing-screws 20 a nice adjustment is obtainable'for the slide 60 and coaoting parts. The lever 124 has an upwardly-extending portion 128, to which is pivoted a spring-rod 129, carrying a spring 130, bearing at one end against an abutment 131, fixed to the guideblock 76, and the other end bearing against a collar 132 on the rod 129. The spring 130 thus tends to hold the bowl 126,into engagement with the cam 127 and raise the slide 60 when the operation has been completed. The guideblocks 76 have secured to their top surfaces a 'plate 133, which carries adjustings' crews 21, the lower end of said screws being so positioned as to engage the upper edge of the slide 60, thus insuring a correct position of the lower edges of the legs 77 78 relatively to the wire. The wire is held firmly in position while the several operations on it are being completed by two gripping-fingers 3O 31,
